ThesisItem Open Access Seed Source Variation for Seed and Seedling Characters in Kair [Capparis decidua (Forsk.) Edgew.](CCSHAU, 2006) Kalu Ram; Bangarwa, K. S.Seeds were collected from five randomly selected trees of Capparis decidua from each of two sites from Rajasthan (Hanumangarh, Bhadra) and Haryana (Sirsa, Hisar) provenances during September 2005. The seeds of all the twenty progenies arising from four provenances were used for provenance testing in nursery and seed storage up to six months. Fruit diameter ranged from 14.79 to 22.88 mm with a general mean of 17.83 mm. Variability for fruit diameter was comparatively higher in Hanumangarh and Sirsa. Analysis of variance showed the presence of significant variation among progenies for germination per cent, plant height and collar diameter, whereas significant variation among provenances were observed for plant height and collar diameter. Medium values of phenotypic coefficient of variation and little difference from genotypic coefficient of variation were observed for all the three characters, viz., germination per cent, plant height and collar diameter. Heritability estimates and genetic advance were also found high for all the characters under study. Progeny number 8 from Bhadra provenance was found overall best for all the three characters viz., germination per cent, plant height and collar diameter. Progeny number 6 from Bhadra was found significantly superior than general mean for plant height and collar diameter whereas progeny number 1 from Hanumangarh was found significantly superior than general mean for germination per cent and plant height. In general, the provenances like Hanumangarh and Bhadra were found superior for seedling characters. Standard germination of fresh seeds varied from 53.74 per cent in progeny no.17 from Hisar to 62.21 per cent in progeny no.1 from Hanumangarh with a mean of 59.08 per cent. The average germination per cent of fresh seed (59.08) was reduced to 44.87 per cent three months after storage and which was further reduced to 32.73 per cent six months after storage. The reduction in both vigour index-I and vigour index-II were observed higher than standard germination for all the progenies up to six months of storage.ThesisItem Open Access Vegetative propagation of Dalbergia sissoo (Roxb.) through stem cutting(CCSHAU, 2006) Praveen Kumar; Bimlendra KumariThe experiment was conducted in the nursery of the Department of Forestry in CCS, Haryana Agricultural University (India) during February and August season of 2003-04. The cuttings taken form 8 to 10 years old tree from three zones of canopy i.e. upper, middle and lower with thickness i.e. 0.5 cm to 1.0 cm diameter (thin) and 1.1 cm to 1.5 cm (thick). These cutting treated with different plant growth regulators viz. indole-3-butyric acid, indole-3-acetic acid, nepthalic acid at three concentration levels i.e. 1000 ppm, 500 ppm, 250 and combination of thiamine with 500 ppm of each growth regulator. The experiment was laid out in completely randomized design with three replication. The results revealed that cutting planted in February season gave better percentage of rooting (60.6%), number of roots per cutting (4.0), root length (12.0 cm) per cutting and weight of roots (0.37g) than August planted cuttings. All the roots characteristics obtained were better with thick cutting than thin cutting and canopy levels followed the trend of lower, middle and upper canopy i.e. cutting from the lower canopy gave best results. IBA 1000 ppm was most effective in sprouting (75.5%) and rooting (66.4%) of Dalbergia sissoo stem cutting. All the PGRs treatment gave significantly better results in both the season with all the canopy levels and with thick as well as thin cutting over control. From the studies, it was concluded that when the cutting of Dalbergia sissoo is taken from lower canopy with diameter 1.1-1.5 cm (thick) treated with indole-3-butyric acid 1000 ppm planted in February season gave the best results with respect to duration of sprouting, percentage of sprouting, number of leaves per cutting, number of roots per cutting, weight of root and shoot, percentage of rooting and rootshoot weight ratio and average length of root per cutting.ThesisItem Open Access Diversity, abundance and pollination efficiency of insect pollinators on seed crop of broccoli (Brassica oleracea L. var. italica Plenck)(CCSHAU, 2014) Suman Devi; OmbirThe present study was conducted at Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana (India). Twenty seven insect species belonging to 14 families under 5 orders were observed visiting the flowers of broccoli. In variety BFT-1, A. dorsata was the most abundant visitor (2.90) followed by A. mellifera (2.30), A. cerana (1.20), A. florea (0.80) and syrphid fly were least frequent visitor (0.20), in variety GH-1 A. mellifera was the most abundant visitor (7.34) followed by A. florea (6.67), A. dorsata (2.15), syrphid fly (1.84) and A. cerana (1.22) and in varieties LPH-1 and DPH-1, A. mellifera was the most abundant visitor (5.96 and 7.00) followed by A. florea (4.46 and 5.50), syrphid fly (2.97 and 3.30), A. dorsata (2.62 and 2.41 ) and A. cerana (1.66 and 2.40). The mean foraging speed, in varieties BFT-1, GH-1, LPH-1 and DPH-1 was maximum in case of A. florea (28.29, 38.54, 37.44 and 36.72, respectively) followed by A. dorsata (5.19, 5.24, 5.24 and 5.20, respectively), A. mellifera (4.54, 4.54, 4.52 and 4.50, respectively ), A. cerana (3.56, 3.51, 3.58 and 3.59, respectively) and syrphid fly (1.90, 2.65, 2.67 and 2.60, respectively). The mean foraging rate in varieties BFT-1, GH-1, LPH-1 and DPH-1 was maximum in case of syrphid fly (14.18, 17.61, 17.42 and 17.33, respectively) followed by A. cerana (10.26, 10.29, 10.27 and 10.32, respectively), A. mellifera (9.27, 10.04, 10.00 and 10.31, respectively), A. dorsata (7.84, 7.88, 7.77 and 7.80, respectively) and A. florea (1.42, 1.71, 1.71 and 1.72, respectively). The average number of broccoli siliqua/plant, siliqua length, number of seeds/siliqua, seed vigour-I, seed vigour-II, test weight and germination per cent under open-pollination were significantly higher than without insect pollination. Number of siliqua/plant, number of seeds/10 siliqua, siliqua length (cm), test weight (g), germination (%) and seed vigour-I, seed vigour-II of uncaged and caged broccoli plants were 3,362.0 and 672.6, 118.75 and 25.85, 6.79 and 3.54, 2.888 and 2.092, 87.50 and 30.25, 1,471.65 and 418.40 and 0.662 and 0.112, respectively.ThesisItem Open Access Incomplete block designs for diallel and partial diallel crosses- A critical review(CCSHAU, 2016) Bishnoi, Rekha; Aneja, D.R.The objective of present investigation is to give an exhaustive review of work done on incomplete block designs for diallel and partial diallel crosses. Confounded diallel crosses for Methods I and III of Griffing (1956) given by Agarwal (1974, 75) are useful when the experimenter is interested in the estimation of all components i.e. g.c.a, s.c.a, maternal and maternal interaction effects of diallel crosses. The loss of information of different effects and interactions has also been given. N-ary designs using triangular PBIB designs given by Divecha and Ghosh (1994) for estimation of g.c.a, s.c.a, reciprocal effects for all four complete diallel crosses can be used. Efficiency of these designs is a matter of investigation. Optimal complete diallel crosses using Nested (Gupta and Kageyama, 1994) & PBIB designs (Dey and Midha, 1996) and efficient designs for complete diallel crosses through Latin square designs (Sharma et al., 2011) & balanced lattice designs (Sharma, 2005) have been also described in the present manuscript. These designs are efficient/optimal for g.c.a effects only. Catalogue of all such designs for number of inbred lines upto 20 have been also given which will be useful for the experimenter in the selection of appropriate blocked diallel cross design as per his requirement. Optimal complete diallel crosses designs given by Chai and Mukherjee (1999) are optimal for both g.c.a as well as s.c.a comparisons. Method of constructing Incomplete Block Designs for Partial Diallel Crosses using n-ary designs given by Agarwal & Das (1990) and Divecha & Ghosh (1997) have been illustrated through examples also. In these methods, two designs have to be considered; one for construction and another for evaluation of Partial Diallel Crosses. When the list of all such BIB and PBIB designs is not available, Mating Environment designs using circular designs (Sharma, 1998) are useful because these are available for any combination of number of treatments and block sizes. Catalogues of such designs have been provided in in tabular form. Construction method of optimal partial diallel crosses by Mukerjee (1997) & Das et al. (1998) available in literature have been also described.ThesisItem Open Access Sequencing of Mx gene in an indian major carp(CCSHAU, 2006) Sharma, Parvati; Sihag, R.C.Mx gene is inducible by type I interferon and is involved in antiviral defenses. Interferons are pleiotropic glycoproteins belonging to a large family of Cytokines. The type I interferon constitute the first line of defence against viral infection in the vertebrate innate immune system. Mx gene inducible by type I interferon, natural and synthetic double stranded RNA (ds RNA) and unmethylated bacterial CpG motif, both in fish and mammalian hosts. Mx expression was observed in fish after viral infection (i.e. IPNV, VHSV, ISAV), although the antiviral role of Mx proteins in fish remains unclear. Mx gene has been cloned and sequenced in many fishes including gold fish and grass carp of family Cyprinidae. The aim of the present study was to standardize the RT-PCR protocol for the expression of Mx gene in an Indian major carp, rohu (Labeo rohita). Mx response was measured in rohu injected with the synthetic double stranded polyribonucleotide Poly I: C (500 μg/fish) and the control fish was injected with PBS alone. Total RNA was extracted from liver of acclimatized fish after 3 days of post-injection. It was transcribed to cDNA and amplification of cDNA was done by RT-PCR. The sequence was obtained from purified gel product. The blasts search was done for confirmation of Mx gene in rohu. It was found 99% matching with grass carp Mx and 98% matching with gold fish Mx3 belonging to family Cyprinidae. These results confirm the presence of Mx gene expression in an Indian major carp, rohu. The obtained partial sequence can be used for taxonomic and phylogenetic purposes.ThesisItem Open Access Weed management studies in maize (Zea mays L.)(CCSHAU, 2006) Bhagirath Kumar; Kamboj, B.R.The present study is entitled as, “Weed management studies in maize (Zea mays L.)”, was conducted at Research area of K.V.K. Damla, Yamuna Nagar (Haryana) under CCS Haryana Agricultural University, Hisar during kharif season of 2004. The experiment was laid out in randomized block design in field with 15 treatments of herbicides and three replications. All the weed control treatments effectively controlled the weed and gave significantly higher yield than weedy check. Post-emergence application of glyphosate (1%) at 45DAS with pre-emergence application atrazine (500 g/ha) provided excellent control of all the weeds till maturity. Pre-emergence application of prometryn (1000 g/ha) fb glyphosate (1%) at 45 DAS and one hoeing at 21 DAS fb glyphosate also provided excellent control Dactyloctenium aegyptium and Cynodon dactylon. Post-emergence application of glyphosate either with pre-emergence application of atrazine or prometryn gave the grain and stover yield statistically at par with weed free treatment.ThesisItem Open Access A study on economics of beekeeping in yamuna nagar district of Haryana(CCSHAU, 2006) Bhupender; Kadiyan, R.S.The study entitled “A study on Economics of beekeeping in Yamuna Nagar district of Haryana” was carried out in Yamunanagar district of Haryana state during 2003-04. It was observed that the expenditure on wooden box with iron stand accounted for 43.49 per cent followed by honey bees, wax sheets and labour costs. The returns from honey accounted for 82.76 per cent followed by bee colonies ( 14.79 ) and bee wax (2.45 ). The net returns were maximum in large category followed medium and small categories. The benefit-cost ratio showed that an investment of Rs. 1 in beekeeping enterprise as overall would fetch a return of Rs 2.19. And it was highest in large sized beekeepers i.e. 2.99. The whole cost invested in beekeeping enterprise was recoverable with in one year. While marketing of honey channel-II (producer-consumer sale at market) was mostly adopted by large beekeepers. The major problems faced by the beekeepers were lack of fair prices of honey and competitions among buyers. However, there is need to develop proper marketing and processing facilities so that the producer can get fair price of their produce.ThesisItem Open Access Standardization of cultivation technology of blue oyster mushroom (Hypsizygus ulmarius) in Haryana(CCSHAU, 2016) Sharma, Pankaj Kumar; Fateh SinghHypsizygus ulmarius (Bull.ex.Fr.) Redhead has been studied to optimize physiological conditions, suitable substrate, supplement and its cultivation to harvest maximum yield. Two cultivation trials were carried out during October - December, 2015 and February – April, 2016 under natural conditions of Haryana. Gram flour (5 %) supplemented wheat straw was treated with hot water (60 0C) and chemicals viz., Bavistin ; 50 ppm, Formalin ; 500 ppm and Bavistin;50 ppm + Formalin;500 ppm. Maximum yield (661 g), least spawn run period (21.9 days), pinhead appearance (23.7 days) and mould incidence (11.7 %) was observed when wheat straw substrate treated with hot water (60 0C for 30 minutes). Physiological study of H. ulmarius was conducted to optimize temperature and pH using PDA medium to obtain maximum growth. Radial growth and biomass were maximum at 25 ±1 0C and pH 7.0.ThesisItem Open Access Bioecology of castor capsule borer, conogethes punctiferalis guenee (Lepidoptera: Pyralidae)(CCSHAU, 2016) Shivakumar K.; Gaur, Ram KaranField and laboratory studies on Bioecology of castor capsule borer, Conogethes punctiferalis Guenee (Lepidoptera:Pyralidae) were carried out at CCS Haryana Agricultural University, Regional research station, Bawal during 2015-16. Studies on biology of C. punctiferalis showed that eggs of this species were pale white, round, oval shaped and found singly or in groups of 4 to 7. The incubation period varied from 4 to 5 days. There were five larval instars and the total larval duration varied from 15 to 20 days. The pupa was dark brown in colour, obtect and pupal period varied from 9 to 11 days. Female moth having tuft of anal hairs but it is absent in case of male moth. Male moths of C. punctiferalis were smaller (mean 21.90��0.70 mm in wing expense) than female (mean 23.40��1.24 mm in wing expense). Adult male lived for 5 to 6 days whereas female for 6 to 7 days. The total life span of male ranged from 34 to 73 days, while that of female from 35 to 76 days in different generations. There was a ifference in sex ratio, being in favour of female both in laboratory and field condition. The pest completed five generations in a year. The presence of brown frass and fecal pellets around the entrance hole was the symptom of infestation of this pest. The observations on pest infestation showed that infestation fluctuated from 2.0 to 14.2 per cent. The peak level of infestation (14.2 per cent) was recorded during November 16-30, 2015. The pest infestation showed negative correlation with maximum temperature (-0.394), minimum temperature (-0.346) and rainfall (-0.121) whereas positive correlation with morning (0.479) and evening (0.206) relative humidity. This pest caused 10.5 per cent seed infestation in castor, 2 to 5 percent damage on guava fruit whereas no infestation was found on ber, aonla and mulberry. The castor capsule borer caused the economic loss an approximately Rs. 7560 per hectare in castor crop.
